The'invention"aslllustrated in the accompanying drawings is shown asbeing applied to the well known standard Royal typewriting machine, butit is to be understood that the invention is adapted to be applied toother types of typewriting machines, or to calculating machines or the40 like. s

The machine, as disclosed, includes a main frame A having a rear wall 5,a carriage B having end plates 6, I, a platen C, a main ribbon D, andtype bar's E which are operated in the usual manner.

The front .portion of the carriage B is supported on the main frame byupper and lower rails 8 and 9, and the rear portion is supported on ahorizontal rail II) which is located in rear of the rear wall 5 of themain frame A. 4

A supply of worksheets W of indeterminate length is positioned in rearof the machine, and the lead-in ends of the sheets are directed upwardlyover a horizontal roller 33 which is' mounted at on the rear-ends ofarms II, II integral with and projecting rearwardly beyond the dependingI legs 2!, II of the carrlageend plates. The leadclamp, or guide '1"wherein they are remcvably clamped, the truck being mounted forline-spacing movements on a vertically disposed stationary collatingframe G located above the platen and supported by the end plates of thecarriage.

Carbon strips 8 which are located between the work sheets Wextend alongthe writing line or the platen C, and are intermittently fed across thework sheets by a mechanism which will be described hereinafter.

The platen C which is of the cylinder type is notmounted forintermittent line-spacing rotary movements asin the usual typewritingmachines, but instead is eccentrically mounted for backward and forwardswinging movements only, as shown particularly in Figimes 6, 7,8, 9, and14. To this end, the cylinder 3! of the platen is provided at its endswith circular heads 40, ll having eccentrically positioned longitudinalbearing hubs l2, 43 for receiving a shaft 44 which is fixedly secured insaid ,hubs 'by screws 45. The cylinder 3! is attached at its ends to theheads ll, 4| by split clamps ll, H which when released permit thecylinder to be angularly adjusted with respect to said'h'eads wheneverit is desired to change the position of the writing place on the platen.The'ends of the shaft pro-1 ject beyond the hubs and are iournaled inbearlugs 40, 48 which are rigidly secured to and project inwardly fromthe end plates I of the carriage B. Rigidly attached to the hub 43isarockarm-Sl asshowninFigurestL'Land 8 particularly, and pivotallyconnected as at Ii to said rock arm is the forward end .of a link II.The rear end of the link I! is pivotally connected as at I! to the arm Iof a three-armed lever ll fixed to the right hand end of a rock shaft 5'which is joumaled at its ends in the end plates 8, 'l of the carrlage.-The platenC is positively rocked to its rearmost or non-writing positionby means of a manually operable carriage return lever I'I whlch.isfulcrumed as at II to oscillate about a vertical axis on a horizontalbracket 5! (Figure 4) which is rigidly secured to and extends outwardlyfrom the front portion of the left end wall 8 of the carriage A. Theinner end of the lever I! is provided with a ",the cam edge portiontla.en-

' left as shown in Figure 1) the lever 62 will gaging a roller IImounted on a lever i! which is pivoted at one end as-at 68 w the bracket58. A link 84 is pivotally connected at its front end as at I to thelever 62, andis pivotally connected at its rear end as at II to thelowerarm I of a lever I which isfixed'to the rock shaft 56. Thus whenthe operator swings the carriage return lever 51 to the right (or to theeffect a rocking of the shaft, which, through the medium of the lever",j'linkll. and rock its rearward or inoperative position as shown in Asabove stated, the. swinging of the carriage return lever II to the right(or to the left as .viewed in Figure 1) eifects a rearwardmove ment ofthe platen C to its inoperative position. Upon release of the carriageretm'n lever by the operator, said lever and platen, together with theoperating connections therebetween, will be returned automatically totheir initial positions. To this end, as shown in Figures 3, 4, and 6,

' the lever 55 which is fixed to the'rock shaft I.

is provided with a forwardlyextending rock ms .69 having a roller 10journaled thereon. A bell crank lever II is pivoted at its angle as atI! on the end plate I-of the carriage B in front of the rock arm-89. Onearm 13 of the bell crank lever .ll extends rearwardly and is providedwith a fork I4 which slidably engages the ,roller 10. The other armIi-of the bell crank lever ll extends downwardly and is connected to theforward end of a coil spring II whose rear end is anchored to the endplate 23 of the carriage. Thus upon release of the carriage return leverll the spring I! will through the medium located eccentrically within'the periphery of the platen; that, when the platen is in its operativeor writing position, the major axis of the eccen-, trically mountedplaten lies in a horizontal-plane which intersects the axis of theplaten and the line of writing of the platen, and consequently the forceof type impact against the platen will be directed against the fixedaxis of the platen; that, when the platen is in its operative or writingposition, as shown in Figure 6, the writing line of the platen will belocated in front of a plane containing the guide roller II and the linespacing truck F and consequently the work sheets W are bowed forwardlyand have relatively tight in rear of the position of the platen writingline when-the latter is in'its operative position; and that whentheplaten is in its inoperative position the work sheets Wand carbonstrips S- will be relieved of their relatively tight contact relationwiththe platenand the carbon strips will return to their normal or flatrelation, whereby the work sheets maybe line spaced without dragging thecarbon strips upwardly therewith and wherebythe carbon strips may be fedfreely through the-work sheets.

. It will be observed that, whenthe platen C is in its operative orwriting pontion, the work sheets W would normally extend upwardly fromthe writing line of the platen to the work clamp F. Consequently thework sheets directly above the writing line of the platen would bespaced from the. platensurface. Thus, when lower case types are beingemployed for printing, the upper case types would strike the work sheetsdirectly above the writing line on the platen, and would result inslight impressions being made on the work sheets by the upper casetypes. Furthermore, by reason of the work sheets being spaced from theplaten directly above the writing line, the upper portions of the lowercase types would not strike the work sheets with the same force as thelower portions of the lower case types, and uneven impressions wouldbe/m'ade on the work sheets. Means are therefore provided for curving orpositioning the work sheets and the carbon strips directly above thewriting line of the platen into relatively tight contact relation withthe platen. at the time when said platen is being returned to itsoperative or writing position, and to 'relieve said relatively tightcontact relation of the work sheets and carbon strips with the platenwhen the latter is being moved rearwardly to its inoperative positionwhereby thework sheets may be line spaced upwardly by movement of thetruck F without dragging the carbon strips upwardly therewith, andwhereby said carbon strips may be fed freely through the work sheets. Tothis end, I have provided a U-shaped positioning ball I'I comprising awork sheet engaging base or arm I8, and spaced rearwardly extending armsI8, 80, the base or arm "I8 being coextensive with the platen anddisposed in front of the work sheets and extending beyond the side edgesthereof, and the armslil, extending rearwardly past the side edges ofthe work sheets and having sliding contact with the heads 40, M of theplaten. Located in therear of the platen is a brace rod 8| secured tosupporting arms 82, 82 which are mounted on the inner faces of thecarriage end plates 8, 1. Pivoted on the supporting arms 82, 82 byshouldered screws 88, 88 and spaced upwardly are upwardly extendingoperating arms 84, to which are pivotally connected at their upper orfree ends as at 88, 81 the free or rear ends'of the arms 19, 80 of thepositioning ball 11. As shown in Figure 5, the arm 84 is pivotallyconnected as at 88 to the forward end of a link 89 having its rear endpivotally connected as at to the upper arm M of the lever 08 which isfixed to the rock shaft 58. As shown in Figure 6, the arm 85 ispivotally connected as at 82 to the forward end of a link 83 having itsrear end pivotally connected as at 84 to the upper arm of the lever 55which is fixed to the rock shaft 58. It will therefore be seen that,when the shaft 56 is rocked by movement of the carriage return lever 51to the right,

the operating arms 84, 85 will be swung forwardly and the positioningbail I1 will be moved forwardly, and that when the carriage return leveris released and returned to its initial position by the spring IS, theoperating arms 84, 85

will be swung rearwardly and thepositioning ball 'I'I will be movedrearwardly to its normal or operative position. It will also 'beobserved that the rock shaft 56 is-,the common driving element for boththe platen C and the positioning bail 11; that when the platen is movedrearwardly the ball will be moved forwardly simultaneously to therebycooperate with the platen movement and relieve the worksheets W fromtheir relatively tight contact'relation with the platen, and that theplaten and the bail are respectively moved simultaneously forwardly andrearwardly to their normal or operative positions at which timethe-positioning bail 'II retains the worksheets directly above thewriting line of the platen in spaced relation to the upper types whenthe lower types are being employed.

The positioning ball I! is yieldably held in sliding contact with theheads 40, 4i of the platen by coil springs 88, 8'! which are located infront of the pivots 88, 81 and have their upper ends connectedto thearmsI9, 80 of the bail and their lower ends connected to lugs 88, 88respectively formed on the upper ends of the operating arms 83, 84 ofthe operating arms 84, 85. By having the arms 78, 80 of the positioningbail resting on the heads 40, H of the platen, the vertical position ofthe base '18 of the bail is always maln- I tained when said bail is inits operative posi- P tion. The positioning bail .11 may be swungupwardly and rearwardly to the dotted line position shown in Figure 5 topermit the work sheets W to be pulled forwardly when loading the machinefor the purpose of interleaving the carbon strips S in said work sheets,or to make erasures on the work sheets. The upward and rearward movementof the positioning ball is limited by laterally extending stop ears I00,IOI respectively formed on the upper end of the operating arms 88, 84,and engageable by the arms I8, 80 of the positioning bail. It will be.

observed that when the positioning ball 11 is swung upwardly to itsinoperative position the springs 88, 91 will cross the pivots 88, 8'!which connect the bail I1 and arms 84, 80 and thereby retain thepositioning bail in said upward position.

The collating'frame G comprises two spaced channel shaped side bars orstandards I02, I03

which are rigidly although removably connected at their upper ends by across bar I04 by means of screws I05, I08 and have their lower ends Ifixed to the bearings 48, 48 of the platen C.

Rearwardlyand downwardly inclined braces I01,

I08 are rigidly although removably connected at their upper ends to thesidebars by screws I08, I I0, and are rigidly connected-at their lowerends by screws III, H2 to the end plates 8, I of the carriage B, tothereby retain the collating frame v in a vertical and stationaryposition.

The rock arm 50 of the platen is'provided with an adjustable stop screw50a (Figures 6, 7,'and. 8) which cooperates with the adjacent standard803 of the stationary collating frame G to thereby variably limit theforward or operative position of the platen C.

It will be observed that the positioning ball 11 is located between theside bars I02, I08 of the collating frame, and consequently said ball isfree.

to be moved forwardly and backwardly and to be swung ,upwardly andrearwardly without interfering with the collating frame.

The truck F is line spaced upwardly 'along the collating frame G by ,thecarriage return lever 51 in timed relation with the backwardand forwardmovements'of the platen C and positioning.

bail 11. The tru'ckF, together with the connections between .the truckand the carriage retum' lever 51,- is disclosed generally in the patentto Degener 1,853,761, of April l2, 1932.

The truck or clamp F '(Figure 11) includes a relatively stationaryclamping plate a: and a relatively movable clamping plate 1 betweenwhich the lead-in ends of the work sheets W are adapted to .be clamped.A manually operable means including a cam I I3 and a finger lever I Inis mounted on the truck for moving the movable clamping plate 1/ againstthe tension of a spring in the clamp, or to release themtherefrom. Thetruck also carries a horizontal shaft II5 having pinions Iii, II1thereon which engage vertical rack bars H0, H0 fixed to the innerflanges of the side bars for maintaining the truck in its horizontalposition when being moved upwardly or downwardly along thecollatingframe.

Removably attached to the outer flange of the standard I02 by screwsI20, I is a stationary and longitudinally extending ratchet bar I2Ihaving ratchet teeth I22 along its rear face. A lifting bar I20 isslidably mounted on the side bar I02 between the rack H0 and thestationary ratchet bar I2I for longitudinal movements relative thereto,and is provided with ratchet teeth I24 along its rear face. Theliftingbar I-20 is provided with spaced upper and lower pairs of guide flangesI25, I25 and I20, I25, and upper and lower pairs of guide pins I21,I21a. and I20, I20a are respectively mounted onthe stationary rack barIll and the stationary ratchet bar I2I for retaining the lifting bar I20in place.

A bracket plate I20 (Figures 10, 11, and 13) is r gidly connected to thetruck or clamp I" and extends rearwardly of theside bar I02 of thecollating frame. A lifting pawl I00 and a holding pawl IOI- arefulcrumed on a pin I02 fixed to the bracket plate I20, the lifting pawlI 00 engaging the teeth of the ratchet lifting bar I20 and the holdingpawl IOI engaging the teeth of the stationary ratchet bar I2I; Thesepawls are normally held in engagement withthe teeth of said ratchet barsby means of coil springs I00 and I04. It will thus be seen that, whenthe lifting bar I20 is elevated, the lifting pawl I00 will cause thetruck 1' to be correspondingly elevated, andwhen pressure is releasedfrom the lifting bar the holding pawl I 0| will'retain the truck in itselevated position. The distance between any two adjacent teeth of thelifting bar correponds to the distance of a single space, and it willtherefore be apparent that as the truck orclamp F is elevatedstep-by-step the work sheets W will be correspondingly line spaced.

A manually operable means including finger pieces I05, I3 is mounted onthe truck F for releasing the pawls I00, IOI whereby the truck may belowered by gravity to the bottom of the collat- .ing frame G wheneverQitis desired to have the truck engage the next form on. the work sheet.

mounted on the. horizontal arm I00 of a bell crank lever I00 which isfulcrumed on a horizontal bearing pin I40 fixed on the end plate .0 .ofthe carriage B. (See Figures 5,11, 1'1, and 18.) The upwardly. extendingorverticalarm I of said bell crank lever I00 is connected by anadjustable eccentric pivot I42 to the rear end of a link I40. (SeeFigures 5 and 11.) The front endof the link I40 is pivotally connected.as at I44 to a lever I 45 which is fulcrumed on the pivot 00 on theshelf 50. (See Figures 4 and 18.) The lever I 45 is provided with aforwardly extending arm I46 which terminates in an upturned toe I41.when the carriage return lever 51 is released, the spring" 10 willeffect a return of the positioning ball 11 and the platen 0 togetherwith the lever 52 to their initial positions, and the lifting bar I20will gravitate to its initial position and thereby eifect a return ofthe lever I45 to its initial position. I v

Journaied on the cam head 00 of the carriage return lever 51 is a rollerI40 which, when the 2,119,814 'I I4 when it is desired to insert thework sheets lever 51 is in its normal position, is spaced a'cons'iderable distance from the toe I41 of the lever I45 and will notcontact said toe until after the lever 51 has actuated the lever 62 toeffect the forward movement of the positioning bail 11 and 5 therearward movemenFof the platen C. After the roller 0| leaves the camedge 60a of the carriage return lever 51, it contacts a concentric edgeportion or dwell 60b. Thus, upon continued movement of the carriagereturn lever to the 10 tions during, the line spacing movement of the gtruck or clamp F, or, in other words, the line spacing of the worksheets will occur subsequent to the platen and the positioning bailbeing respectively moved rearwardly and forwardly to relieve the normaltight contact relation of the go work sheets, and carbon strips with theplaten. When the carriage return lever 51 is released, the spring 15will effect a return of the positioning ball 11 and the platen .0together with the lever to their initial positions, and the lifting barI 20 willgravitate to its initial position and thereby effect a returnofthe lever I45 to its initial position, a

In the event that it is desired to employ a new form of work sheet W ofdifferent line spaco ing, it will be necessary to substitute a newratchet bar I2I and anew lifting bar .I20 having teeth of differentpitch. This is accomplished by revmoving the screws I20 from thestationary ratchet bar I2I and sliding the link I01 laterally oi! theheadless stud I01a, and then removing the lifting bar I20 and thestationary ratchet bar I2I through the top of the collating frame G;This,

removal of the bars I2I and I23 can be effected only after the.- cross'bar I04 and the braces I01. have been partly disassembled by removingthe screws I05, I06, I00, and H0. It will be understood that the pawlsI00, IOI will be held out of engagement with the teeth of said bars I2I,I 20 during the time the substitution is being made. 5

It will also be observed that by means of the adjustable eccentric pivotI42 the amo unt of lifting movement imparted to the lifting bar I20 maybe adJusted to conform to the line spacing arrangement of the new worksheet W.

assemblies 8 which are journaled on a frame- I40 which is mounted on therear of the carriage B. for horizontal forward and backward movementstransversely of the machine. 4

The carbon strips 8 of the respective sets of a spool assemblies are ledfrom the spo'ols around horizontal guide pins 220 which are fixed to andextend rearwardly from the spool plate I;

thence around three sets of vertical rolls 224 mounted on a shelf 225attached to the end plate ranged in a row; thence forwardly towards theg5 carriage return lever 51; thence around a single roll 225 mounted onthe front end of the shelf 225; thence along in front of the platen Cand in interleaved relation with the work sheets W;

thence around-a single roll 221 mounted on a shelf 220 on the carriageend plate 1;- and thence rearwardly to a strip feeding mechanism Y whichis mounted on the shelf 220 and is identical with that shown in theDegener Patent 1,853,761, said feeding means including a pair offeedrollers 7r The carbon strips S are unwound from spool 12s, 2!! whichare positively actuated through the medium 01 a link 230 (Figure 3)connected The mechanism for mounting and feeding the carbon strips 8 isdisclosed and claimed in my co-pending application Serial No. 92,241,'flled July 23,1936.

iF'rom the foregoing it' will be observed that the eccentric axis of theplaten is located within a circle prescribed by the arcuate writing lineof the platen, and consequently therearward and upward movement of theplaten is fast and the normal tight contact relation between. the worksheets and the platen is relieved in a very rapid manner so as to permitthe carbon strips to be fed through the work sheets with a minimumamount of friction; that the major axis of the platen contains thewriting. line of the platen, and consequently the force of impact by thetype bars will be directed against the fixed axis of the platen; thatthepositionlng bail functions normally to prevent the upper types fromcontacting the'work sheets, and'is. movable forwardly in timed relationwith the rearward movement of the platen to free the work sheets priorto the strip feeding operation and prior to the line spacing movement ofthe work sheets; and that the ratchet bars of the line spacing mechanismmay be readily removed and others substituted whenever it is desired tovary the amount of line space imparted to the work sheets.
